COMBINED MAGNET AND VALVE.

Application filed September rhis invention relates to improvements in pine organs, particularly to the valve nie-clifor controlling the passage of `air to the pipes, and it consists oA the constructions, comhinations and arrangements herein described and claimed.

in object ot' the invention is to ixuovido a 'elitively small instrument coiuhini' 'alve and the electroai'iagnet forrcontroi t, several of the important lieatnres b compact structure, the reduction oli par o a minimum number and the inode of assembling the parts on such order that dis assemblv for replacement and regali is readil;7 accomplished.

Other objects and advantages will appear in the following specification, reference being had to the accompanying lrawing, in which Figure 1 is a cross section oit Wind chest illustrating the installation of the improved combination magnet and diaphragm valve, the electro-magnetbeing deenergized with the result that the organ pipe is silient.

In carryingl ont the invention7 provision is made ot a base 1 which has a boss 2 rigidly carrying the hair pin electro-magnet The Winding of the electro-magnet included in a circuit comprising` the generator (in, the Wire it which connects one side of the winding to one side of the generat .r, the wire that connects the other side of the Winding with a lined Contact 6 and a Wire 7 that connects the other` side of the generator with the movable switch 8.

foregoing circuit to energize the electro-mag` net.

The result oil this energizatioi'i will. be the attraction of the armature f). This armature is fat-ed at 10 and 11 with shin. It is mounted upon stud 1.1l in the valve cover 1Q, its 'unction being to either close the air opening 1? upon energizaton of the electro-magnet or to close the ori. ,e 19t. The latter 'lu-notion occurs when Ihe electro-magnet is deenerg'ized. the armature valve 9 then .seatingY bv gravity. i' .A

1t is the purpose of the electro-magnet 3 and armature valve 9 to control the action, a valve seating on the opening 16. ln the base '1, or upon the air outlet 17 and actuating through air controlf a bellows valve admitting or closing ofij the admission of air to the organ pipe. The valve 15 seats on the opening 1G when the magnet is energized or drops by gravity upon the air outlet 17 when the electro-magnet is deenergized. The former act permits exhaustion to atmosphere oli air Within the bellows 13 so that the organ pipe valve 1S) uncovers the air opening 530 ot the organ pipe 21, the latter act permitting an equalization of pressure between the interior of the bellows 18 and the interior the wind chest so that the bellows spring 23 causes seating ot the valve 19 for the closure otl the opening' 20.

The Valve' 15 is composed of a fiber washer which is '5i ced on opposite .sides by telt7 shin or other suitable w: hers 2li and Q5. 'llie valveY t 2li is threaded at 27' down to and et he location ot the air valve, (lug. rThe threads are utilized both to hold the valve and to permit such adjustment therei'ii as to location as may be reunired. The threads also support a liber washer 28 at the upper end. The puit or diaphragm 29 is secured to this Washer.

A ring 3() clamps the diaphragm 29 at the peripheiiT in position in the diaphragm or puit chamber 31. The diaphragm divides the chamber into tivo. and the distinction is herein made by referring to one as the upper pn i chamber, and the other as the lower puff chamber. The attachment ot the valve stein to the diaphragm serves to guide the upper end of the stem. The other end passes throng a small bracket 3Q (Fig. which guides the loWcr end. The ring 30 is grooved at 33 (Fien. 1 and 3) to place the upper puff chamber into communication With a duct 34 in the base 1. The lower end ot the duct conimunicates with the interior ot the valve cover 12, and when the armature valve 9 is normally seated 4upon the orifice le the upper puitq chamber contains air at wind chest pressure.

Communication between the lower putt1 chamber and the interior of the base 1 had through a pair oit passages (Figs. 2, 3 and l). These are divided by a bridge 35 (Fie Ll) in which the duct 3e is bored or othe formed. The passages 35 are cu through the'bottom of the base 1, bi nication is not had with the cause the passages are cover 37 of the armature valve cc Communication between tlie i wind chest and the lower p1, through the pasK .ges 35 is peinia Y when the armatu valve 9 is seated orifice 14;. .statedbelore, air at wind chest pressure is obviously also present in the lower puit chamber. The equalize-d pressure on both sides of the diaphragm 29 permits the valve 15 to gravitate to its seating position upon the air outlet 1'?. Air trom the wind chest then enters the interior ol the bellows 18 by way ot the passages 35, the valve cap 38, bore 39 in the base 1 and bore l0 in the wind chest. The resulting 'equalization ci" pressure inside and outside of the bellows permits the spring 23 to seat thevalve 19.

Screws llat diagonally opposite corners oit the basel (or elsewhere it desired) serve to nire the base upon the windchest A gaske 42 (Figs. 1 and 2) is interposed. The wind chest has an opening 43 to admit the magnet 3. The cover 12 is held in placev by a bent pin 44;. Y The upper end ol2 this pin is riveted at 45 (Fig. 3) to hold it in place upon the base 1. The pin is intended to be turned over in position beneath the cover (Fig. 5) at which time it rides upon an arcuate enlargement il@ which permits a wedge action. Screws Ll? (F Ll) hold the guide bracket 32 in place. A thin water 18 or cardboard or Yother air sealing material lits upon the ring 30 to cover the upper puff chamber so that the security oil el is chamber need not rely upon the in'nncdiately surrounding portion of the gasket The operation isreadily understood. The inoperative position is illustrated in lliejure 1. The switch 8 is open and the electroni net 3 is deenergized. The wind chest 22 contains air under pressure. and the armature valve 9 closes the orifice lll both by virtu-e et the air pressure upon it andrbyv lgravity. The Valve 15 also gravitates to the closed position upon the air outlet 17 in vthismanner: rl`he opening 13 being uncovered admits air from the wind 'chest to theinterior ot the `cover 12 whence it enters the duct 34 and groove 33 and occupies the upper pull chamber. Air enters the lower puff chamber by way olf the passages 35. rlhe resulting equalization ot presM sure at both sides oit the diaphragm permits Aed from speaking.

,sembled the aforesaid gravitation. Under the same condition air also enters the interior of the bellows 1S, as can readily be seen in Figure 1, so that there is equalization of pressur both on the inside and outs-ide of the bellows. The spring 23 therefore seats thev valve 19 upon the opening 2O so that the pipe 21 is preven"- Upon depression of the switch 8, (which may be regarded as an organ key) the electro-magnet 3 becomes energized by virtue ot the closure of the electric l circuit. The armature valve 9 is then attracted to close the open ng 13. This preve the entrance et under pressure fro i the wind chest 22 to the interior loit the cover 12. Agir troni the upper pull' cha. ilicr therefor e7;- hausts to atmosphere tl'irough ther groove 33, duct 3l, interior ol' t ie cover 12 and orifice le. vloweve wind chest air pressure prevails in the lower pull chamber by virtue. the perpetual communication ai'lorded by the passages 35. The unbalancing of tie pressures causes the diaphragm 29 to riso (Fig that the valve 15 is pressed up and ov op .up The valve is held i..t inl on by virtue of the predominating area or 'the r.lhe foregoing action of the valve 15 uncovers the air outlet 17 so that the air in the bellows 13 ernausts to atmosphere. The resulting unbalancing ot pressures causes the collapse of the bellows and the uncoveringv of the opening 20. Air under pressure then enters the organ pipe 21 andthe pipe is caused to speak.

One of the outstanding purposes of the invention is to produce a compact combined air control valve andinagnet for controlling it. rlhe instrument tal-res up but very little more space than the average magnet7 and this is a matter et no mean importance because space generally a matter ol serious consideration in pipe organ structure. Such air valves are usually oit considerable and are maf'. separately from the electro-magiu-ts that control them. Ent here the parts have been so redesigned to combine the elements inl o a relatively small space without sacrificinn` any original advantage.

ln fact. the compacting oli the elements establishes new advantages. The closeness ot the armature valve 9 inahes it rpossible'to operate the electro-.magnet 3 with small current. Although the parts are lirmly put together, they are9 nevertheless, readily disas- The cover 12 is taken oil by 'simply turning the bent pin le (Fig. he cap 38 is removed bv simply taling out the two screws V7 whicn hold the bracket 32 in place. rlhe e 'e instrument is taken ott by simply 1 -l Y the y ie ore an.
